Summary
OpenClaw's non-default autoAllowSkills setting could bypass on-miss exec prompt
Details

Summary

In openclaw versions up to and including 2026.2.22-2, a non-default exec-approval configuration could allow a skill-name collision to bypass an ask=on-miss prompt.

When autoAllowSkills=true, a path-scoped executable such as ./skill-bin could resolve to basename skill-bin, satisfy the skills allowlist segment, and run without prompting for approval.

Affected Packages / Versions

  • Package: npm openclaw
  • Affected versions: <= 2026.2.22-2
  • Patched versions: >= 2026.2.23 (released)

Configuration Scope (Not Default)

This behavior requires non-default settings and does not affect default installs.

Required conditions: - autoAllowSkills=true (default is false) - system.run with security=allowlist - ask=on-miss

Technical Details

The allowlist evaluator accepted skills satisfaction by bin-name match, so ./skill-bin could match skillBins.has("skill-bin") after resolution.

The fix hardens skill auto-allow matching by requiring: - a pathless invocation token (no / or \\), and - a trusted resolved executable path for that skill bin on the machine where skills run.

This preserves normal skill-bin ... behavior while preventing ./<skill-bin> and absolute-path basename collisions from auto-satisfying skills.

Impact

In affected non-default configurations, approval prompts could be skipped for commands that should have required operator confirmation.

Fix Commit(s)

  • ffd63b7a2c4c6d5aeb4710ef951d5794ad7ad77b (fix(security): trust resolved skill-bin paths in allowlist auto-allow)

OpenClaw thanks @tdjackey for reporting.
